Single Board Computers (SBCs) are self-contained single circuit boards and microprocessors designed to perform a range of computing tasks. The VL-EPM-31EAP is a type of SBC with the ARM9-MPC8250 processor. It includes a memory controller and registers, a internal memory, a programmable memory controller, an Ethernet controller, an interrupt controller, a programmable timer, an 8-bit parallel data bus, an I2C bus and external memory interface, a UART, and a USB controller. The SBC can be powered by 5V DC.

The VL-EPM-31EAP application field includes medical instrumentation, industrial process control, image processing, image storage, communication systems, embedded systems, etc. It is capable of offering rich satisfaction to customers with its low thermal design power consumption and real-time Linux/RTOS/WinCE systems. It also has extended memory support through a peripheral component interconnect (PCI).

The working principle of VL-EPM-31EAP is based on the ARM9-MPC8250 processor. It has 32MB SDRAM, 32MB Flash, Ethernet PCA88A, UART 0/1, RS-232 and 4 USB ports. It also supports two external devices, one SD card slot and one IDE interface with the support of PCMCIA bridge. The ARM9-MPC8250 processor operates in little-endian mode when writing data to its internal memory and in big-endian mode when writing data to external memory. It also has an internal timer and a watchdog timer.

The VL-EPM-31EAP uses a 9-bit address bus to access its internal memory and a 16-bit data bus to access its external memory. The processor is programmed using either C or Assembly language. It supports the real-time operating system (RTOS) that is responsible for managing task scheduling, memory management, and interrupt handling. The RTOS includes a set of primitives for task creation, signal handling, context switching, synchronization, and scheduling. It also supports a set of network protocols like TCP/IP and UDP.

The VL-EPM-31EAP has a high degree of integration with its on-board peripheral devices. It is capable of communicating with external devices through USB, Ethernet, serial, and I²C. It also has an integrated hard-drive interface that supports two types of hard drives, SCSI and IDE, allowing it to boot from hard disks. This on-board hard-drive interface also provides additional data storage options for its users.

The VL-EPM-31EAP offers a wide range of application areas due to its low thermal design power consumption and real-time Linux/RTOS/WinCE systems. It is suitable for applications in medical instrumentation, industrial process control, image processing, image storage, communication systems, and embedded systems. It also helps users to easily develop systems with its highly integrated on-board peripheral devices. This SBC provides a great value for its customers with its versatility, affordability, and top-tier performance.
